I've got the following (quoted from my confirmation email) from Sorat Tires shipped to me in Ottawa fron Vancouver (
www.soratwheels.ca):
BMW M6 Replica wheels with 245/45/18 Bridgestone Blizzak LM 25 Runflat tires, TPMS sensors, mounted+balanced, shipped to your door for $2195cdn + tax
I have (well technically waiting for delivery of) a 2011 55i xDrive with mSport. The car has the 19" wheels but the the slection listed above has the same circumference. The rims are good match to the mSport rims.
